Japan Post offers a "frame stamp" service where you can include your own images on legal stamps. To commemorate Ayumi Hamasaki's 10 years in the music business, Shibuya Post Office in Tokyo, in partnership with Avex, is offering a sheet of stamps featuring her album covers. They are not an official Japan Post stamp series but Shibuya has set up a booth to sell them and may plan other designs if the idea proves popular. While you won't be able to buy these stamps directly from other post offices, you will be able to apply for them or else order them through the Enpos catalogue.
